🛡️ FAQ: XLPPI Electrical Interfaces
1. What is an XLPPI electrical interface?
The XLPPI (Extended Low-Power/Low-Voltage Parallel Interface) electrical interface is a high-speed, low-voltage, parallel electrical connection used in modern optical transceivers such as QSFP+, QSFP28, QSFP56, and QSFP-DD. It defines how high-speed electrical signals move between a host system (switch, router, NIC) and the optical module.
2. What is the purpose of the XLPPI interface in optical transceivers?
XLPPI ensures reliable high-speed electrical signaling over short distances on the host PCB. Its primary purpose is to maintain signal integrity, support multi-lane parallel data architectures, minimize power consumption, and enable seamless interoperability between hosts and modules.
3. What speeds does XLPPI support?
Depending on the generation of the host and optical module, XLPPI supports:
10 Gbps per lane (QSFP+ / 40G)
25 Gbps per lane (QSFP28 / 100G)
50 Gbps per lane PAM4 (QSFP56 / 200G)
100 Gbps per lane PAM4 (QSFP-DD / 400G & 800G roadmaps)
4. How does XLPPI differ from SFI or CAUI interfaces?
SFI is serial, typically used for SFP+/SFP28 single-lane modules.
CAUI/CAUI-4/CAUI-8 are IEEE-defined multi-lane interfaces for 100G/400G links.
